1 European Telecommunications Standards Institute Grid Specialist Task Force Interoperability Gap Analysis

2 ETSI Motivation TC GRID STF 331 Technical Report 1: Grid Stakeholders Technical Report 2: Interoperability Gaps

European Telecommunications Standards Institute Standards body for Information and Communications Technology officially recognized by European Commission 700 member organizations 60 countries

3 European Telecommunications Standards Institute Standards body for Information and Communications Technology officially recognized by European Commission 700 member organizations 60 countries represented Located in Nice, France Responsible for GSM standard (2.3 billion users) Prolific in creating ICT standards: 65 in 2006 with 1400 Tech Specs 3GPP 3G Partnership Project NGN Next Generation Network TISPAN - Telecommunication and Internet converged Services and Protocols for Advanced Networking

4 Large national network providers Strong requirement (legal/regulatory) for Backwards compatibility (PSTN) Very high availability (> % 3 sec/year down-time) Well established network and service architecture Slow changing Well defined (standard) protocols Well documented Large test suites to validate implementation conformance

5 Deregulation Multiple network operators Multiple service delivery agents VoIP/SIP, Skype, GTalk Fixed/Mobile convergence 3G/4G mobile services Ubiquitous Wi-Fi, Wi-MAX, GPRS, UMTS Mobile Internet Continuous integration of new services and features Standards? What standards? TCP/IP Focus is Internet connectivity by any means, then just TCP/IP

6 Impacts large user base Majority of world population, across economic boundaries Network/Infrastructure issues Authentication/Authorization/Billing questions Large pool of hardware manufacturers End user units Switches Servers Large pool of value-added service providers Large pool of network operators Everything (or at least most of it) needs to work together!

7 Grid Technical Committee formed in 2006 Mandate to: Monitor convergence of IT and Telco domains, including grid computing initiatives Report to ETSI members on standards for interoperability Identify interoperability gaps Liase with other standards organizations Members include FranceTelecom, British Telecom, Telefonica, IBM, Alcatel-Lucent, and others Propose actions to ETSI to improve ICT standards for Grid interoperability and report on state of the art to ETSI members

testing framework Website acting as resource for ICT (Telco/Grid) stake-holders Formed in

8 Specialist Task Force with 4 deliverables: Inventory of ICT read Grid/Telco stake holders Identify grid interoperability gaps Specifically from enterprise/telco perspective Grid testing framework Website acting as resource for ICT (Telco/Grid) stake-holders Formed in October experts, each contributing days per year 2 year time line, approx 400 person-days work

9 Large scale Scalable Dynamic Inter-operable Extensible Secure Heterogeneous Non-trivial service provision Usable Manageable For purely pragmatic reasons, the following NFRs are optional: Federated Geographically distributed Reliable

10 Next Generation Network (NGN): Person-to-Person services Messaging services Content-on-Demand services Grid and NGN: Subsystem Application Interfacing network Combo

11 TC GRID views OGF as primary source for grid software standards Memorandum of Understanding signed during OGF20 Still, several other relevant standards bodies ETSI among them Referencing, not repeating, work of SCRM-WG Standards development organizations Collaboration on networked Resources Management Focus on Telco-relevant and Telco-scale grid standards Software and protocols Architectures Data Standards Networking

12 Clarity on the state of Grid Standards Which are relevant Which are stable Which can be (and have been) implemented Visibility of standards and interoperability gaps Where will they need an ad hoc bridge? Where will they need to write new standards Identify opportunities for Telcos to utilize and provide grid computing Storage services Service hosting Bandwidth-on-demand Generic compute-on-demand Transition identities from Internet/Grid/Web world to Telco world Exposing network APIs to grid layer

13 Engagement of a major industry Improved exposure to and expertise on existing telco standards for Network management Identity management, user profiles, accounting, billing High availability services Standards conformance testing strategies Heads up for 3G/4G and NGN telco technology currently in the pipeline Ubiquitous network availability (e.g. WiMAX) Move to packet based/ip network New services available to users and developers New requirements and use cases

14 Distributed Management Task Force (DMTF) Common Information Model (CIM) well known in Telco domain Web Based Enterprise Mgmt (WBEM) CIM API ETSI GRID Security, Web Services, IT/Telco convergence TISPAN responsible for NGN and IP/packet based network IETF Security - X.509, SASL, TLS Network - IPv6

15 OASIS Security - XACML, SAML Web Services - UDDI Architecture Service Component Architecture (SCA) W3C XML, XSD XML Security SOAP

16 Reality is much of grid computing takes place outside of standards Monolithic systems Fixed configurations Limited inter-grid interoperability Need to learn from experience of real implementations EGEE/WLCG TeraGrid OSG Grid5000 D-Grid NorduGrid And other national/regional grids

provides APIs for valueadded services and hooks into underlying network infrastructure 1.

17 Fixed and wireless phone network(s) WORK Large Reliable Evolving Commercial There are Users Data Networks Software Hardware Issues around security, billing, service layering, gateways have all been addressed NGN provides APIs for valueadded services and hooks into underlying network infrastructure 1. Grid developers/standards could learn from these existing standards 2. Enterprise and/or Large-Scale Grid computing could leverage this infrastructure

Interoperability through new protocols/interfaces How to measure

18 Interoperability through adapters Interoperability through uniform deployment Interoperability through existing protocols/interfaces Interoperability through new protocols/interfaces How to measure interoperability? Good question! Look for advice from OGF, GIN ETSI PlugTest tradition Work in progress
